Angular: ng-show and functions

Question

Say you have a template like

<a ng-show=function()>a link</a>

My question is: when is function run? How can I tell angular that it is time to re-run the function?

Answer 1

Well, ng-show takes a Boolean value, so your best option for using it is to call your function somewhere in the logic that sets ng-show.

$scope.show = false;

$scope.showSomething = function(myCondition){
    if(myCondition){
        myFunction();
        $scope.show = true;
    }
};

<div ng-show='show'></div>
